Patent number: 10983263Abstract: An eyepiece and waveguide for viewing a projected image in a virtual reality and augmented reality imaging and visualization system. The waveguide may include a substrate for guiding light. The waveguide may also include an incoupling diffractive element disposed within or on the substrate and configured to diffract an incoupled light related to the projected image into the substrate. The waveguide may further include a first grating disposed within or on the substrate and configured to manipulate the diffracted incoupled light from the incoupling diffractive element so as to multiply the projected image and to direct the multiplied projected image to a second grating. The second grating may be disposed within or on the substrate and may be configured to outcouple the manipulated diffracted incoupled light from the waveguide. The first grating and the second grating may occupy a same region of the waveguide.Type: GrantFiled: August 22, 2017Date of Patent: April 20, 2021Assignee: Magic Leap, Inc.Inventors: David Kleinman, Samarth Bhargava, Victor K.
